CUE is the first and only smart grid engine that integrates HVAC operations in buildings with grid operations and markets to simultaneously lower building and grid expenses. CUE’s software as a service (SaaS) application features an automated, scalable energy-optimization system designed to maximize comfort, reduce costs, extend equipment life, and support corporate sustainability goals. CUE harnesses thermal mass in large commercial office buildings— in the form of concrete, drywall, books, and desks—and uses it to store cooling energy during off-peak times. CUE essentially turns buildings into batteries™ capable of energy storage on a multi-MW scale.
